You should just need to restart the placeholder service if anything.
Also, what version are you? Seems you might have to mis-spell it...;)

BypassRecallLimitsForAdmins will not work when using the correct spelling
Details:
In the registry guide the registry key BypassRecallLimitsForAdmins is documented with two Ls in Recall but the Enterprise Vault code is actually looking for Recall with one L.
Workaround:
When creating the registry key create it with one L.
HKEY_LOCAL_MACHINE\Software\KVS\Enterprise Vault\FSA\PlaceholderService\BypassRecalLimitsForAdmins
